A new school year has begun again in Yamiyama, but this year... It will be a little different~
If the "dead person" is conscious, he knows that he is the dead person from the beginning;
If that tape hidden in the old classroom was heard by everyone...
Killings, bizarre murders, classmates from Class Three of the third year died tragically one after another. Whose unwillingness is causing the commotion?
When the dead don't want to return to death, when the "innocent" people don't want to be the next to die...
Kill! Start!
Deceased? ! Who is it? !
